A step device includes: a plurality of steps arranged so as to be lined up in a railcar width direction and constituting a part of a floor surface; and drive mechanisms configured to cause the steps to move upward and downward at a railcar-width-direction inner side between an upper position at which the plurality of steps become a part of the floor surface and a lower position at which the steps are moved downward to constitute boarding stairs. Each of the drive mechanisms includes a rotating link configured to rotate about one end portion thereof in a vertical plane, connecting links respectively connecting the rotating link to the steps, and an actuator configured to cause the rotating link to rotate. The steps move upward and downward by the rotation of the rotating links via the connecting links. |
